    • Well worth 40 bucks!!
Number of Items: 1
This sub sounds really clean, hits way better than expected. Plenty enough and sounds great for my set up. I like bass but dont want 40 subs and 8 billion watts. Very nice for my needs and set up. Pushing a 300 watt amp bridged at 2 ohm and this speaker. Sounds great.

    • One of these turns heads at the stop light!!
Number of Items: 1
I bought this exact Hifonics HFX12D4 12" sub from an audio store here in Las Vegas. This guy has a little shop setup in a store called "Savers". He had all kinds of car stuff, such as subwoofers, amps, various gauges of wiring, etc. My wife and I were there about a month ago shopping for her first sub. We tested 4 different brands(Sony XPlod, Pioneer, Kenwood and a Kicker) all of which were 12" speakers. They all sounded great. I mean they sounded really good. Then one box design caught my eye, and the price was right so I told the guy to hook it up. It had this 12" Hifonics sub inside. He hooked it up and played a song and immediately I knew this sub was the one. The bass was so natural, I mean it hit the lows so perfectly. The deep bass notes breathed like a beast hot and heavy like some sort of mythical dragon. The punchy bass notes were always on time, CLEAN and CLEAR! It's hit every high-low bass note really well. I don't know why some other reviewers say that it hits those notes bad. Maybe it's a matter of musical taste which makes the sub perform differently. I listen to all sorts of music, even Japanese music and I hear all bass notes just fine. I sometimes have to reduce the bass on my head unit because it literally doesn't miss a note but back to the store...... It's like, the louder he turned it up, the better the speaker sounded, it was just sickeningly orgasmic so I bought it right then and there for $100(ported box included). She has it in her Ford Explorer and she likes listening to loud music of all genres and whenever she's pulling up in the driveway, you know it's her because the windows shake. SooooOOOOOo. I went back to this same place 2 weeks ago after blowing this cheap 400W old Pioneer sub(it was smoking and everything. I had to pull over because I thought something was on fire). It just so happened he got another Hifonics sub(HFX12D4), that was a 12" also. I bought that one for $100(ported box included). Now, my wife and I both have Ford Explorers, with Crunch 800W amps, and 4 Polk DB571 Door Speakers with Sony 660UP dash receivers so everything's pretty much identical in our vehicles. I recommend this stereo receiver as well because you can personally tune just about every setting(EQ, HPF,LPF,Subwoofer Level,ALO, DM+, Loudness, and a bunch of other sound options to get your music sounding just right). Our subwoofer box designs are a little different, both ported, but we still get a bunch of head turns when we're out driving. I was just out tonight cruising down The Strip with my radio turned up halfway(25); and people on both sides of the Strip stopped doing what they were doing turned towards the street to see where the music was coming from. I've had people at stop lights literally roll their windows up next to me because the music was so loud. I get at least one compliment a day from people watching me approach them as I'm driving down the street. Some people will waive their hands at me, some will start dancing along with the music, some will just stare. Now I'm not saying this is the best sub in the world; there could be better sounding ones out there but from my own personal experience with this sub, having just ONE, ONLY ONE in my car with the equipment that I have(which isn't even that powerful), this is probably better than anything you'll find out there, and for the price...man. Get these subs while you can! You will NOT be disappointed in the amount of power you can drive into these things and they'll still sound flawless. They're lightweight and hit harder than you'll ever know. Trunks will rattle, mirrors will vibrate, you will wonder why you haven't gotten one of these sooner. I am ordering another one as we speak. One is way more than I could ever have anticipated, way more than enough. I just want to see how two would sound. ... show more

Review Image by Manuel Perez
I received this yesterday and wired it up in parallel , bringing it to 2ohm and connected it to my amp bridged . I was playing it all day perfectly fine up until I decided to put my volume up a little bit higher than usual . Within 5 minutes it went out and started smelling burnt. I had blew it . Today I tried messing with it to see what was the problem and it looks like a voice coil broke or something cause I hear a lot of rattling . It still plays and has some bass but not enjoyable . ... show more

    • Good sub just make sure to read the manuals this fixes many issues you'll potential have
Number of Items: 1
This is a great little sub when configured correctly. My Specs are 1 x Hifonics HFX12D4; 1 x Best Balance BT700 mono block Class D amp, Sealed 1.25 cubic ft box with a Net volume of 1.10 cubic ft. Sub is wired to 2 ohms subsonic filter is set to ~22Hz Low Pass Filter set to ~80Hz try for ~90HZ if you want more punch. Make sure to feed this sub at least 400W RMS if you go way over and don't account for it box size you'll blow it give it too little power and you'll blow it as well. This is by far the best sub on amazon under $50usd at the time of writing. if you want a better sub but not want to spend a lot more the Primus 1200 in the same size enclosure with give you better sound and thump due to it's higher sensativit. ... show more

I purchased this thing around eight years ago to go in a budget set up with an AMP I picked up at a good will. This thing sounds fantastic with a hurricane style ported box. The only issue I ever had with it was that the plastic bit they glue onto it came loose and started to rattle. I tore that junk off and it works great, when I bought it, it was 33 bucks, but even at 50 it's a steal when compared to other subs. I've gone through a number of cheap subs, in kits from amazon, one from walmart, and hand me downs. On a budget I it's hard to get better than this. If you really want a pounding and you listen to a lot of high bass music, put it in a 2 cubic food volume box, this thing hits like a ton of bricks in a big box but I had to downsize the box to fit it in something else when it left my pickup. It's currently sitting in a 1.5 cubic foot box that it does better over all (the 2 footer isn't as strong once you leave super low frequencies) I'm genuinely sad I can't get to this thing or it's accompanying amp since there sitting in military storage for now. ... show more

    • Surprised in performance, don't over power them.
Number of Items: 1
These subs can get down low decently. Honestly they need a bigger motor setup but that's not 3 Kings Audio's problem thats HiFonics problem. I'm using an ARC Audio fd2200 to push these and sometimes I smell voice coil throughout the car but I think thats due more to clipping/slight overpower. I have these in a ported box tuned to 33 hz and they will get ridiculously loud. They will rattle houses from 100 to 200 feet away as people on my street have complained to me already. It's a good cheap buy, however I'm switching to Audio Technix Tropo 12's this week. They're better subs with a much harder kick with a lower power rating. ... show more
